[PDF][PDF] Chinese zero pronoun resolution: A joint unsupervised discourse-aware model rivaling state-of-the-art resolvers
We propose an unsupervised probabilistic model for zero pronoun resolution. To our
knowledge, this is the first such model that (1) is trained on zero pronouns in an
unsupervised manner;(2) jointly identifies and resolves anaphoric zero pronouns; and (3)
exploitsdiscourseinformationprovidedby a salience model. Experiments demonstrate that
our unsupervised model significantly outperforms its state-of-the-art unsupervised
counterpart when resolving the Chinese zero pronouns in the OntoNotes corpus.

Experiments demonstrate that our unsupervised model significantly outperforms its state-of-the-art unsupervised counterpart when resolving the Chinese zero pronouns in the OntoNotes corpus.
